These instructions only relate to linear pneumatic actuators which comply with VDI/VDE 3847 with rod-shaped pillars:
For the other actuator types, please contact us.
A – Check that the base (item 1) supplied with the unit is intended for this type of actuator.
It must have two ¼” gas pneumatic openings (item 2 - connections not supplied) on the side, to supply the actuator
chambers).
B – Separate the unit (item 3) from the base (item 1) by unscrewing the 6 M4 screws (item 4) (TORX T20 screwdriver).
C – Remove distribution plate A or B (item 5) with its two seals (item 6)
D – Fit a washer (item 9) and an O-ring (item 8) on each of the 4 M5 screws (item 7)
E – Tighten these 4 screws onto the base (item 1) with the 4 low-profile nuts (item 11)
F – Fix the base (item 1) to the plate (item 12) by tightening the 4 screws (item 7) and the washers (item 13) and nuts (item 14)
The base can be positioned every 180° according to requirements/ constraints
G – Mount the fluted rivet (item 15’) on the driver (item 15). Mount the unit onto the shaft (item 1’) and tighten with the nut (item
17) and washer (item 16)
H – Reposition distribution plate A or B (item 5) with its two seals (item 6)
Check that the seal is correctly positioned (item 10)
I – Position the unit (item 3) on the base (item 1) taking care to engage the white shaft of the unit with the shaft (item 1) of the
base and tighten the 6 M4 screws (item 4) (TORX T20 screwdriver)
J – Mount the sub-assembly (item 18) fitted with the washer (item19) on the plate (item 20) by tightening it onto the
counterplate (item 21)
K – Fix the assembled plate (item 20) onto the valve slider (item 24) with the screws (item 22) and washers (item 23).
L – Fix the plate (item 12) to one of the actuator pillars using the plate (item 25) by tightening the 4 screws (item 26) and the
washers (item 27) and nuts (item 28)
Adjust the position of the plate (item 12) and the sub-assembly (item 18) so that the sub-assembly (item 18) slides in the driver
(item 15) (without exiting) over the entire valve stroke.
